Hi all. I just turned 40 and my husband and I are still TTC. I had a miscarriage in Nov, heart broken, and now I am pregnant again. I am really scared since Saturday I passed what appeared to be a blood clot, then lite bleeding back to brown. Monday I went to my OB and she completed a transvaginal US and did not see a sac. I should have been exactly 5 weeks. I was told that my lining was thick and it could just be early. I am really worried about having another MC. I have had off an on lite bleeding, nothing but spots on the pad and very lit to moderate cramps, sore feeling in my stomach. My OB did the HCG/Progesterone labs on Monday and I go back tomorrow for more labs so they can compare the results. Does anyone have any advise. I am really trying not to worry or stress out but it is kinda hard. Thanks
